Blockspace
The scarce resource a blockchain sells — bytes of data the network agrees to include in its next block, priced by the fee market. The economic core of every chain.
Every blockchain at its core is a market for blockspace: the bytes the network agrees to include in its next block. Demand varies (mempool size, gas estimates, perp basis, NFT mint hype); supply is fixed by protocol parameters (gas limit, block time). The intersection sets the fee market.
Blockspace economics drive almost every higher-level design choice: rollups exist because L1 blockspace is too expensive for most use cases; EIP-4844 added blob blockspace as a cheaper category; restaked DA layers compete on per-byte cost. Treating "blockspace" as the actual unit of trade clarifies what crypto infrastructure is really selling.
